A. Bleed Air Supply Source from the HP Ground Connection
NOTE : The HP ground supply source must be able to give a pack inlet
____ pressure of 24 PSI minimum. If it can not do this then you must get the bleed air supply from the engines. The work steps which follow show the conditions necessary before you get the minimum pack-inlet pressure.

(1) Do the pre-conditioning through the HP ground connection (Ref. AMM TASK 12-33-21-618-001).
(2) On the AIR COND panel 30VU:
- push the HOT AIR pushbutton switch to the on position (the OFF legend goes off),
- turn the COCKPIT, FWD CABIN and the AFT CABIN temperature selectors to the HOT positions and,
- make sure that the PACK 1 and the PACK 2 pushbutton switches are in the on position (the OFF legends are off).
(3) On the ECAM BLEED page:
- make sure that the pack 1 inlet pressure indication shows a minimum of 24 PSI.
NOTE : If the indication shows less than 24 PSI you must:
____
- increase the ground pressure supply until the indication shows a minimum of 24 PSI.
B. Start the engines (Ref. AMM TASK 71-00-00-710-003) if necessary.
C. Initial Test Set-up with Engines as Bleed Air Source Supply
(1) On the AIR COND panel 30VU:
- push the HOT AIR pushbutton switch to the on position (the OFF legend goes off),
- turn the COCKPIT, FWD CABIN and the AFT CABIN temperature selectors to the HOT positions and,
- make sure that the PACK 1 and the PACK 2 pushbutton switches are in the on position (the OFF legends are off).
(2) On the ECAM BLEED page:
- make sure that the pack 1 inlet pressure indication shows a minimum of 24 PSI.
NOTE : If the indication shows less than 24 PSI you must slowly
____ adjust the throttle levers until you get the minimum indication of 24 PSI.
